' WAVE-MOTOR.

SPECIFICATION forming part of Letters Patent No. 562,317, dated June 16,1896.

Application filed November 21,1895. Serial Ila 569,608. (No model.) i

To all whom it may concern.-

Be it known that 1, CHARLES R. MARTIN, a citizen of the United States,residing at Redondo, in the county of Los Angeles and State that classof ocean-motors employing a piv oted lever having a float attachedthereto.

One difficulty to be overcome with devices of this class arises from thevarying inclination of the lever, owing to the'rise and fall of thetides. This variation makes it difficult to transmit the power from thelever to; the motor, and necessitates the use of some what complicateddevices therefor and these devices are liable to get out of order whenmost needed.

One object of my invention is to produce an exceedingly simple device ofthis class which may be readily adjusted to suit the rise and fall ofthe tides.

It frequently happens that vessels lie for a long time at a wharf. Thisis true especially of lumber and coal vessels which at times lie formonths tied up alongside of a wharf. The

power developed by the action of the waves upon a vessel is enormous butheretofore no satisfactory way of utilizing such power has been devised,since such'vessels are necessarily anchored in such a manner as to allowthem to move back and forth to a certain ex tent. This makes itdifficult to'attach the vessel to a motor arranged upon a wharf or otherstationary support, by a connection which will apply the power from thevessel to the motor and yetwill not be broken or cause the motor to bebroken by reason of the varied movements of the vessel with relation tothe wharf.

A further object of my invention is to produce a device which may beattached to a vessel anchored alongside of a wharf, in such a manner asto cause the device to be operated by the motion of the vessel, thus toactuate a pump to pump water into an elevated reservoir from whichit maybe drawnas'desired and utilized for running hydraulic motors, the powerfrom which may be utilized for any purpose desired.

by a vessel.

Figure 1 is a side elevation of a wharf with my invention in positionthereupon, and arranged to be operated by an ordinary float. Fig. 2 is afragmental side elevation of my device arranged upon acar and to beoperated Fig. 3 is an end view of the same looking from the seaward endof the wharf. Fig. 4 is a fragmental detail showing the means foradjusting the device tothe rise and fall of the tides.

In the drawings, A represents the wharf or pier which extends from theshore (not shown) out into the ocean or other body of water.

In Fig. l B represents a float-actuated leverwhich is pivoted to avertically-adjustable support 0. To the upper end of this support ispivoted a walkingbeam D, which is connected by means of a piston-rod Ewith the float-actuated lever.

F G represent two pumps which are secured to the wharf and are providedwith pumprodsf 9, which are respectively secured to the walking-beam bymeans of pivoted pitmanrods f g. Each pump is'provided with asuet-ion-pipe F G, respectively, which extends downward into the Water,and is provided at its top with a discharge-pipe FG, respectively, whichcommunicates with the main II which leads to an elevated reservoir. (Notshown.)

The vertically-adjustable support 0 is engaged by guide-wheels c c,which hold the support in its upright position. Suitable means areprovided for readily adjusting the support 0 with relation to the wharf.Such means, as shown, consist of a cog-rack 0 secured to the support anda pinion I meshing with such cog-rack andprovided with crankarms 1', bywhich the pinion may be rotated to raise and lower thevertically-adjustable support. A ratchet I is arranged to control themovement of the pinion. In Fig. 4 I have indicated in dotted lines aWindlass W and a rope W attached to such Windlass and extending.downward along the support 0, to which it is attached, so that byoperating the Windlass the support may be adjusted vertically. Any othermeans for adjusting the support may be employed without departing fromthe spirit of my invention. The pumpcylinders are made of sufficientlength to allow the horizontal adjustment of the walkmg -beam withoutimpairing the operation of the pumps.

.T represents a windlass upon which is wound one end of a rope J theother end of which is attached to the float K, so that the float can beraised from the water, if desired.

In Figs. 2 and 3 I have illustrated what I deem the most eifectivemanner of applying the power to the motor. This consists of a float L,which maybe avessel, if conveniently anchored for this purpose. Thisfloat or vessel is provided with an upwardly-projecting mast L, to whichthe lever is attached by means of a cable L. My improved motor isarranged upon the wharf and, as shown in Figs. 2 and 3, is mounted on acar M, so that the motor may be moved along the wharf to bring it intoproper position with relation to the vessel by which it is to beoperated.

The water-main II is provided with a series of nipples h arranged alongthe main at suitable intervals, so that the motor may be moved wheredesired and yet the pumps may be readily connected with the main bymeans of the hose h, as shown in Fig. 2.

The 'ertically-adjustable support G is provided with a cog-rack and apinion, as described hereinbefore, whereby to adjust the support toaccommodate the motor to the rise and fall of the tide. In order thatthe motor as thus arranged shall operate effectively, it is essentialthat one end of the lever be of suflicient weight to operate the pumpswhen the lever is allowed, by the movement of the float, to lower, asshown in Figs. 2 and S. In these figures I have shown a suitable weight0 arranged upon a lever, and have in Fig. 3 indicated in dotted linesthe cable passing down and around a pulley l, thence upward and attachedto the lever, and also have. indicated an extension of the lever beyondthe pivotal point, and a weight arranged thereupon, to thus show that itis immaterial to the operation of the device which end of the lever isweighted, but the form as shown in solid lines in the drawings ispreferable for the reason that it is more economical as regards space,and also requires less material in its construction.

The arrangement of the pumps, walkingbeam, &c., is the same in Figs. 2and 3 as it is in Fig. 1, excepting that I have shown the flangedsupporting-wheels c 0 arranged above the car to engage the movablesupport to retain it in its upright position, instead of arranging suchwheels below the wharf, as shown in Fig. 1.

In Figs. 1 and 3 P indicates a guide-frame for the lever B. This frameis provided with a series of pin-holes p, through which a pin or bolt Pis passed to limit the downward motion of the lever. In Fig. 2 thisguide is broken away for the purpose of more fully showing thearrangement of parts.

In practice, in the form shown in Fig. 1, the pump-rods being connectedwith the walking-beam D, and the float K and the lever B being alsoconnected with the walking-beam, as the waves raise and lower the float,the power is transmitted through the medium of the lever and thewalking-beam and thus operates the pumps F G to draw water from theocean and force it through the main II to an elevated reservoir. (Notshown.) hen the tide rises or falls, so that the walking-beam D standsat too great an angle with relation to the horizon, the support O isadjusted by means of the pinion and cog-rack to raise or lower thesupport, as the case may be, until the walking-beam is brought into itsproper position.

In Figs. 2 and 3 the lever is attached by means of a cable L" to themast of the float, but the cable may be attached to a boom or anyportion of the rigging suitable for the p ur pose. As the waves raiseand lower the float or vessel the motion is transmitted through themedium of the mast and cable and thus raises and lowers the end of thelever.

The weight 0 upon the lever B tends to force the lever downward and issufficient to operate the pump upon its downstroke. 13y reason ofattaching the actuating-cable to the mast at a point considerably abovethe end of the lever the swaying of the mast will operate the levereffectively and the flexible connection therebetween will allow lateralmovement of the mastwith relation to the motor without breaking thelever.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a wave-motor, the combination of the support provided at its topwith a walkingbeam; a weighted lever pivoted to such sup port; apitman-rod connecting the lever and the walking -bea1n; pumps connectedwith the walking-beam; a float; and a flexible connection leading fromthe float to the lever and arranged to operate the lever in oppositionto its weight.

2. A wave-motor having a vertically-adj ustable upright support providedat its top with a walking-beam; a float-actuated lever pivoted by oneend to the vertically-adjustable support and having its other endoperatively connected with a float; such float; a pitman rod connectingthe walkingbeam with the lever; a suitable pump connected with theWalking-beam, and suitable means for adjusting the support,substantially as set forth.

8. In a wave-motor, the combination of the Vertically-adjustable supportprovided at its top with a walking-beam; a weighted lever pivoted tosuch support; a pitman-rod connecting the lever and the walking -beam;pumps connected with the walking-beam; a float; and a flexibleconnection leading from the float to the lever and arranged to operatethe lever in opposition to its weight.
